Buenos Aires (English: Fair Winds, originally Ciudad de la Santísima Trinidad y Puerto de Santa María de los Buenos Aires, City of the Holy Trinity and Port of Saint Mary of the Fair Winds) is the capital of Argentina and its largest city and port, as well as one of the largest cities in Latin America and the world. Buenos Aires is located on the southern shore of the Río de la Plata, on the southeastern coast of the South American continent, opposite Colonia del Sacramento, Uruguay.
Argentines sometimes refer to the city as Capital Federal to differentiate the city from the province of the same name. The people of Buenos Aires are known as porteños (English: People of the port), acknowledging the major historical importance of the port in the development of the city and the whole nation.
